Here's your example cleaned up a bit to show just that latest example, and also showing how it looks when adapting a built-in type: https://go2goplay.golang.org/p/eFIvHocOC75 It's possible to build a generic adaptor type from the value-style interface to the pointer-style interface, which you might find interesting: https://go2goplay.golang.org/p/NiQY_-kWvu8 This could *almost* work on image.Point, except that Point.Mul has the wrong signature. cheers, rog. > > . > > -- > You received this message because you are subscribed to the Google Groups > "golang-nuts" group. > To unsubscribe from this group and stop receiving emails from it, send an > email to golang-nuts+unsubscr...@googlegroups.com. > To view this discussion on the web visit > https://groups.google.com/d/msgid/golang-nuts/CAADvV_vxU7nUJ16X5xwBYhiOPVrzp%3DzrX%3DU4UTgBsOQJ2RnMuQ%40mail.gmail.com > . > -- You received this message because you are subscribed to the Google Groups "golang-nuts" group.
